	Note 1—Organization and Basis of Presentation

	Organization

	Plains GP Holdings, L.P. (“PAGP”) is a Delaware limited partnership formed on July 17, 2013 to own interests in the general partner entities of Plains All American Pipeline, L.P (“PAA”), a publicly traded Delaware limited partnership.

	On October 21, 2013, PAGP completed its initial public offering (“IPO”). Immediately prior to the IPO, certain owners of Plains AAP, L.P. (“AAP”) sold a portion of their interests in AAP to PAGP, resulting in PAGP’s ownership of an approximate 21.8% limited partnership interest in AAP. AAP is a Delaware limited partnership which directly owns all of PAA’s incentive distribution rights and indirectly owns the 2% general partner interest in PAA. AAP is the sole member of PAA GP LLC (“GP”), a Delaware limited liability company, which directly holds the 2% general partner interest in PAA. Also, through a series of transactions with PAGP’s general partner and certain owners of Plains All American GP LLC (“GP LLC”) prior to the IPO, PAGP became the owner of a 100% managing member interest in GP LLC, a Delaware limited liability company formed on May 2, 2001, and GP LLC’s general partner interest in AAP became a non-economic interest. Prior to these transactions and as of September 30, 2013, GP LLC held a 1% general partner interest in AAP. See Note 15 for further discussion regarding the completion of PAGP’s IPO and other related items.

	GP LLC manages the business and affairs of PAA and AAP. Except for certain matters relating to PAA that require the approval of the limited partners of PAA, and certain matters relating to AAP that require the approval of the limited partners of AAP or of PAGP as the sole member of GP LLC, either pursuant to the governing documents of PAA, AAP or GP LLC, or as may be required by non-waivable provisions of applicable law, GP LLC has full and complete authority, power and discretion to manage and control the business, affairs and property of PAA and AAP, to make all decisions regarding those matters and to perform any and all other acts or activities customary or incident to the management of PAA and AAP’s business, including the execution of contracts and management of litigation. GP LLC employs all domestic officers and personnel involved in the operation and management of PAA and AAP. PAA’s Canadian officers and personnel are employed by Plains Midstream Canada ULC.

	PAA engages in the transportation, storage, terminalling and marketing of crude oil and refined products, as well as in the processing, transportation, fractionation, storage and marketing of natural gas liquids (“NGL”). The term NGL includes ethane and natural gasoline products as well as propane and butane, products which are also commonly referred to as liquefied petroleum gas (“LPG”). When used in this document, NGL refers to all NGL products including LPG. Through PAA’s general partner interest and majority equity ownership position in PAA Natural Gas Storage, L.P. (NYSE: PNG), it also owns and operates natural gas storage facilities.

	Unless the context indicates otherwise, the terms “Plains,” “we,” “us,” “our,” “ours” and similar terms refer to PAGP, GP LLC, AAP, GP and PAA and its consolidated subsidiaries. Our business activities are conducted through three operating segments: (i) Transportation, (ii) Facilities and (iii) Supply and Logistics. See Note 12 for further discussion of our operating segments.

	Basis of Consolidation and Presentation

	The accompanying unaudited condensed consolidated financial statements of GP LLC represent the predecessor financial statements of PAGP, which are based on the historical ownership percentages of GP LLC and AAP. Prior to the transactions immediately preceding the IPO, PAGP had no assets and PAGP had not conducted any activity through September 30, 2013 since its formation on July 17, 2013. These financial statements have been prepared from the separate financial records maintained by GP LLC and may not necessarily be indicative of the actual results of operations that might have occurred if PAGP had operated separately during those periods. In addition, the effects of the IPO and related equity transfers occurring in October 2013 are not reflected herein.

	The accompanying unaudited condensed consolidated financial statements include GP LLC, all of its wholly owned subsidiaries and those entities that it controls. Under generally accepted accounting principles in the United States (“U.S. GAAP”), GP LLC consolidates AAP and PAA and its subsidiaries. Amounts associated with the limited partner units not owned by GP LLC are reflected in our results of operations as net income attributable to noncontrolling interests and in our balance sheet equity section as noncontrolling interests.

	The accompanying unaudited condensed consolidated interim financial statements should be read in conjunction with PAGP’s final prospectus dated October 15, 2013 (the “Final Prospectus”) included in its Registration Statement on Form S-1, as amended (SEC File No. 333-190227). These financial statements have been prepared in accordance with the instructions for interim reporting as prescribed by the Securities and Exchange Commission (the “SEC”). All adjustments (consisting only of normal recurring adjustments) that in the opinion of management were necessary for a fair statement of the results for interim periods have been reflected. The condensed balance sheet data as of December 31, 2012 was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America (“U.S. GAAP”). The results of operations for the three and nine months ended September 30, 2013 should not be taken as indicative results to be expected for the full year.

	Subsequent events have been evaluated through the financial statements issuance date and have been included in the following footnotes where applicable.

	Potential Acquisition of Publicly-held Common Units of PNG

	On October 22, 2013, PAA announced its entry into a definitive agreement and plan of merger (the “Merger Agreement”) with PNG that provides for a merger whereby PNG will become a wholly-owned subsidiary through a unit-for-unit exchange (the “Merger”). Under the terms of the Merger Agreement, PAA will issue 0.445 PAA common units for each outstanding PNG common unit held by unitholders other than PAA, plus cash in lieu of any fractional PAA common units otherwise issuable in the Merger. There are approximately 33.0 million PNG common units owned by unitholders other than PAA and consummation of the transaction is expected to result in the issuance of approximately 14.7 million PAA common units. Prior to PAGP’s IPO, but subject to consummation of the Merger on terms generally consistent with PAA’s then existing proposal, the owners of AAP agreed to reduce their incentive distribution rights under PAA’s Partnership Agreement by $12 million in each of 2014 and 2015, $10 million in 2016 and $5 million per year thereafter.

	The closing of the Merger is subject to the satisfaction of certain conditions, including the approval of the Merger and the Merger Agreement at a special meeting of the unitholders of PNG by the affirmative vote of holders of a majority of the outstanding PNG common units (including PNG common units held by PAA) voting as a separate class and the affirmative vote of holders of a majority of PNG’s outstanding subordinated units voting as a separate class. PAA owns 100% of the membership interests in the general partner of PNG, 100% of the outstanding subordinated units of PNG and approximately 46% of the 61.2 million outstanding common units of PNG. Pursuant to the Merger Agreement, PAA agreed to vote its common units and subordinated units in favor of the Merger. PAA anticipates that the Merger will close in the latter half of the fourth quarter of 2013 or the first quarter of 2014. The previously announced quarterly distribution of $0.3575 per PNG common unit payable to holders of record of such units on November 1, 2013 was paid on November 14, 2013 as scheduled.

	Note 2—Recent Accounting Pronouncements

	Other than as discussed below and in our 2012 Consolidated Financial Statements included in the Final Prospectus, no new accounting pronouncements have become effective or have been issued during the nine months ended September 30, 2013 that are of significance or potential significance to us.

	In March 2013, the FASB issued guidance regarding the release of cumulative translation adjustments into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity. This guidance becomes effective beginning after December 15, 2013. We will adopt this guidance on January 1, 2014. Our adoption is not expected to have a material impact on our financial position, results of operations or cash flows.

	In February 2013, the FASB issued guidance requiring an entity to present either in a single note or parenthetically on the face of the financial statements (i) the amount of significant items reclassified from each component of AOCI and (ii) the income statement line items affected by the reclassification. This guidance became effective for interim and annual periods beginning after December 15, 2012. We adopted this guidance during the first quarter of 2013. During the nine months ended September 30, 2013 and 2012, all reclassifications out of AOCI were related to derivative instruments. Other than requiring additional disclosure, which is included in Note 10, our adoption did not have an impact on our financial position, results of operations or cash flows.

	In July 2012, the FASB issued guidance intended to simplify the impairment test for indefinite-lived intangible assets other than goodwill by giving entities the option to first assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired. The results of the qualitative assessment would be used as a basis in determining whether it is necessary to perform the two-step quantitative impairment testing. An entity can choose to perform the qualitative assessment on none, some or all of its indefinite-lived intangible assets, or may bypass the qualitative assessment and proceed directly to the quantitative impairment test. This guidance is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted in certain circumstances. We adopted this guidance on January 1, 2013. Our adoption did not have a material impact on our financial position, results of operations or cash flows.

	In December 2011, the FASB issued guidance requiring disclosures of both gross and net information about recognized financial instruments and derivative instruments that are either (i) offset in accordance with the specified sections of GAAP or (ii) subject to an enforceable master netting arrangement or similar agreement. In January 2013, the FASB amended and clarified the scope of these disclosures to include only (i) derivative instruments, (ii) repurchase agreements and reverse repurchase agreements and (iii) securities lending transactions. This guidance is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. We adopted this guidance on January 1, 2013. Other than requiring additional disclosure, which is included in Note 10, our adoption did not have an impact on our financial position, results of operations or cash flows.

Accounts Receivable	'
	Note 3—Accounts Receivable

	Our accounts receivable are primarily from purchasers and shippers of crude oil and, to a lesser extent, purchasers of crude oil, NGL, natural gas and refined products terminalling and storage services. These purchasers include, but are not limited to refiners, producers, marketing and trading companies and financial institutions that are active in the physical and financial commodity markets. The majority of our accounts receivable relate to our crude oil supply and logistics activities that can generally be described as high volume and low margin activities, in many cases involving exchanges of crude oil volumes.

	To mitigate credit risk related to our accounts receivable, we have in place a rigorous credit review process. We closely monitor market conditions in order to make a determination with respect to the amount, if any, of credit to be extended to any given customer and the form and amount of financial performance assurances we require. Such financial assurances are commonly provided to us in the form of standby letters of credit, parental guarantees or advance cash payments. At September 30, 2013 and December 31, 2012, we had received approximately $122 million and $173 million, respectively, of advance cash payments from third parties to mitigate credit risk. Furthermore, at September 30, 2013 and December 31, 2012, we had received approximately $452 million and $343 million, respectively, of standby letters of credit to support obligations due from third parties, a portion of which applies to future business. In addition, in an effort to mitigate credit risk, a significant portion of our transactions with counterparties are settled on a net-cash basis. Further, we enter into netting agreements (contractual agreements that allow us to offset receivables and payables with those counterparties against each other on our balance sheet) for a majority of such arrangements.

	We review all outstanding accounts receivable balances on a monthly basis and record a reserve for amounts that we expect will not be fully recovered. We do not apply actual balances against the reserve until we have exhausted substantially all collection efforts. At September 30, 2013 and December 31, 2012, substantially all of our accounts receivable (net of allowance for doubtful accounts) were less than 30 days past their scheduled invoice date. Our allowance for doubtful accounts receivable totaled approximately $4 million at both September 30, 2013 and December 31, 2012. Although we consider our allowance for doubtful trade accounts receivable to be adequate, actual amounts could vary significantly from estimated amounts.

	In February 2013, PAA signed a definitive agreement to sell certain refined products pipeline systems and related assets included in our Transportation segment. At December 31, 2012, these assets were classified as held for sale on our condensed consolidated balance sheet (in “Other current assets”). On July 1, 2013, a portion of the transaction closed with the sale of certain of the refined products pipeline systems and related assets. The remaining assets were classified as held for sale on our condensed consolidated balance sheet as of September 30, 2013. PAA closed the balance of the transaction during November 2013.

	(1) Price per unit of measure represents a weighted average associated with various grades, qualities and locations. Accordingly, these prices may not coincide with any published benchmarks for such products.

	At the end of each reporting period we assess the carrying value of our inventory and make any adjustments necessary to reduce the carrying value to the applicable net realizable value. We recorded a non-cash charge of approximately $7 million during the three and nine months ended September 30, 2013, primarily related to the writedown of our crude oil inventory due to declines in prices during the period. During the three and nine months ended September 30, 2012, we recorded non-cash charges of approximately $7 million and $128 million, respectively, related to the writedown of our crude oil and NGL inventory due to declines in prices during the period. The recognition of these adjustments in 2013 and 2012, which are a component of “Purchases and related costs” in our accompanying condensed consolidated statements of operations, was substantially offset by the recognition of gains on derivative instruments being utilized to hedge the future sales of our crude oil and NGL inventory. Substantially all of such gains were recorded to “Supply and Logistics segment revenues” on our condensed consolidated statements of operations. See Note 10 for discussion of our derivative and risk management activities.

	(1) In 2013, we renewed and extended our principal bank credit facilities. See “Credit Facilities” below for further discussion.

	(2) We classify as short-term certain borrowings under the PAA commercial paper program, PAA senior unsecured revolving credit facility and PAA senior secured hedged inventory facility. These borrowings are primarily designated as working capital borrowings, must be repaid within one year and are primarily for hedged NGL and crude oil inventory and NYMEX and ICE margin deposits.

	(3) We classify as short-term debt any borrowings under the PNG senior unsecured revolving credit facility that have been designated as working capital borrowings and must be repaid within one year. Such borrowings are primarily related to a portion of PNG’s hedged natural gas inventory.

	(4) PAA’s $250 million 5.63% senior notes will mature in December 2013 and are thus classified as short-term at September 30, 2013 and December 31, 2012.

	(5) In August 2013, PAA completed the issuance of $700 million, 3.85% senior notes due 2023 at a public offering price of 99.792%. Interest payments are due on April 15 and October 15 of each year, commencing on April 15, 2014.

	(6) PAA’s fixed-rate senior notes (including current maturities) had a face value of approximately $7.0 billion and $6.3 billion at September 30, 2013 and December 31, 2012, respectively. We estimated the aggregate fair value of these notes as of September 30, 2013 and December 31, 2012 to be approximately $7.5 billion and $7.3 billion, respectively. PAA’s fixed-rate senior notes are traded among institutions, and these trades are routinely published by a reporting service. Our determination of fair value is based on reported trading activity near quarter end. We estimate that the carrying value of outstanding borrowings under our credit agreements and commercial paper program approximates fair value as interest rates reflect current market rates. The fair value estimates for our senior notes and borrowings under our credit agreements and commercial paper program are based upon observable market data and are classified within level 2 of the fair value hierarchy.

	Commercial Paper Program

	In August 2013, PAA established a commercial paper program under which it may issue, from time to time, privately placed, unsecured commercial paper notes for up to a maximum aggregate amount outstanding at any time of $1.5 billion. Such notes are backstopped by the PAA senior unsecured revolving credit facility and the PAA senior secured hedged inventory facility; as such, any borrowings under the commercial paper program reduce the available capacity under these facilities.

	Credit Facilities

	In August 2013, the PAA senior secured hedged inventory facility and PAA senior unsecured revolving credit facility agreements were amended to, among other things, extend the maturity dates of the facilities by two years. The facilities now mature in August 2016 and August 2018, respectively. Also in August 2013, the maturity dates of the PNG senior unsecured revolving credit facility and GO Bond term loans were extended by one year to August 2017.

	In September 2013, the AAP credit agreement was amended to increase the term loan facility from $200 million to $500 million, increase the aggregate commitments under the revolving credit facility from $25 million to $75 million and extend the maturity date by one year to September 2018.

	Borrowings and Repayments

	Total borrowings under our credit agreements and commercial paper program for the nine months ended September 30, 2013 and 2012 were approximately $13.2 billion and $8.5 billion, respectively. Total repayments under our credit agreements and commercial paper program were approximately $13.4 billion and $7.8 billion for the nine months ended September 30, 2013 and 2012, respectively. The variance in total gross borrowings and repayments is impacted by various business and financial factors including, but not limited to, the timing, average term and method of general partnership borrowing activities.

	Letters of Credit

	In connection with our supply and logistics activities and natural gas storage and commercial marketing activities, we provide certain suppliers with irrevocable standby letters of credit to secure our obligation for the purchase of crude oil, NGL and natural gas. Additionally, we issue letters of credit to support insurance programs and construction activities. At September 30, 2013 and December 31, 2012, we had outstanding letters of credit of approximately $42 million and $24 million, respectively.

Derivatives and Risk Management Activities	'
	Note 10—Derivatives and Risk Management Activities

	We identify the risks that underlie our core business activities and use risk management strategies to mitigate those risks when we determine that there is value in doing so. Our policy is to use derivative instruments for risk management purposes and not for the purpose of speculating on hydrocarbon commodity (referred to herein as “commodity”) price changes. We use various derivative instruments to (i) manage our exposure to commodity price risk as well as to optimize our profits, (ii) manage our exposure to interest rate risk and (iii) manage our exposure to currency exchange rate risk. Our commodity risk management policies and procedures are designed to help ensure that our hedging activities address our risks by monitoring our derivative positions, as well as physical volumes, grades, locations, delivery schedules and storage capacity. Our interest rate and currency exchange rate risk management policies and procedures are designed to monitor our derivative positions and ensure that those positions are consistent with our objectives and approved strategies. When we apply hedge accounting, our policy is to formally document all relationships between hedging instruments and hedged items, as well as our risk management objectives for undertaking the hedge. This process includes specific identification of the hedging instrument and the hedged transaction, the nature of the risk being hedged and how the hedging instrument’s effectiveness will be assessed. Both at the inception of the hedge and on an ongoing basis, we assess whether the derivatives used in a transaction are highly effective in offsetting changes in cash flows or the fair value of hedged items.

	Commodity Price Risk Hedging

	Our core business activities contain certain commodity price-related risks that we manage in various ways, including the use of derivative instruments. Our policy is to (i) only purchase inventory for which we have a market, (ii) structure our sales contracts so that price fluctuations do not materially affect our operating income and (iii) not acquire and hold physical inventory or derivatives for the purpose of speculating on commodity price changes. The material commodity-related risks inherent in our business activities can be divided into the following general categories:

	Commodity Purchases and Sales — In the normal course of our operations, we purchase and sell commodities. We use derivatives to manage the associated risks and to optimize profits. As of September 30, 2013, net derivative positions related to these activities included:

	· An average of 316,500 barrels per day net long position (total of 9.8 million barrels) associated with our crude oil purchases, which was unwound ratably during October 2013 to match monthly average pricing.

	· A net short spread position averaging approximately 32,800 barrels per day (total of 13.0 million barrels), which hedges a portion of our anticipated crude oil lease gathering purchases through December 2014. These derivatives are time spreads consisting of offsetting purchases and sales between two different months. Our use of these derivatives does not expose us to outright price risk.

	· An average of 13,700 barrels per day (total of 1.7 million barrels) of crude oil grade spread positions through January 2014, which hedge anticipated purchases and sales of crude oil. These derivatives are grade spreads between WTI and various other grades of crude oil including WTS, LLS and Brent. Our use of these derivatives does not expose us to outright price risk.

	· An average of 2,500 barrels per day (total of 1.4 million barrels) of butane/WTI spread positions, which hedge specific butane sales contracts that are priced as a percentage of WTI through March 2015.

	· A net long position of approximately 1.3 Bcf through April 2016 related to anticipated base gas requirements.

	· A short position of approximately 29.4 Bcf through January 2014 related to anticipated sales of natural gas inventory.

	· A short position of approximately 10.7 million barrels through March 2015 related to the anticipated sales of our crude oil, NGL and refined products inventory.

	Storage Capacity Utilization — We own a significant amount of crude oil, NGL and refined products storage capacity other than that used in our transportation operations. This storage may be leased to third parties or utilized in our own supply and logistics activities, including for the storage of inventory in a contango market. For capacity allocated to our supply and logistics operations, we have utilization risk in a backwardated market structure. As of September 30, 2013, we used derivatives to manage the risk of not utilizing approximately 2.2 million barrels per month of storage capacity through December 2013. These positions involve no outright price exposure, but instead enable us to profitably use the capacity to store hedged crude oil.

	Pipeline Loss Allowance Oil — As is common in the pipeline transportation industry, our tariffs incorporate a loss allowance factor that is intended to offset losses due to evaporation, measurement and other losses in transit. We utilize derivative instruments to hedge a portion of the anticipated sales of the allowance oil that is to be collected under our tariffs. As of September 30, 2013, our PLA hedges included a net short position for an average of approximately 1,700 barrels per day (total of 1.4 million barrels) through December 2015 and a long call option position of approximately 0.6 million barrels through December 2015.

	Natural Gas Processing/NGL Fractionation — As part of our supply and logistics activities, we purchase natural gas for processing and NGL mix for fractionation, and we sell the resulting individual specification products (including ethane, propane, butane and condensate). In conjunction with these activities, we hedge the price risk associated with the purchase of the natural gas and the subsequent sale of the individual specification products. As of September 30, 2013, we had a long natural gas position of approximately 16.3 Bcf through March 2015, a short propane position of approximately 2.9 million barrels through March 2015, a short butane position of approximately 0.9 million barrels through March 2015 and a short WTI position of approximately 0.3 million barrels through March 2015. In addition, we had a long power position of 0.5 million megawatt hours which hedges a portion of our power supply requirements at our natural gas processing and fractionation plants through December 2015.

	All of our commodity derivatives that qualify for hedge accounting are designated as cash flow hedges. We have determined that substantially all of our physical purchase and sale agreements qualify for the NPNS exclusion. Physical commodity contracts that meet the definition of a derivative but are ineligible, or not designated, for the NPNS scope exception are recorded on the balance sheet at fair value, with changes in fair value recognized in earnings.

	Interest Rate Risk Hedging

	We use interest rate derivatives to hedge interest rate risk associated with anticipated debt issuances and outstanding debt instruments. The derivative instruments we use to manage this risk consist primarily of interest rate swaps and treasury locks. As of September 30, 2013, AOCI includes deferred losses of approximately $76 million that relate to open and terminated interest rate derivatives that were designated for hedge accounting. The terminated interest rate derivatives were cash-settled in connection with the issuance or refinancing of debt agreements. The deferred loss related to these instruments is being amortized to interest expense over the terms of the hedged debt instruments.

	PAA entered into forward starting interest rate swaps to hedge the underlying benchmark interest rate related to forecasted debt issuances through 2015. The following table summarizes the terms of these forward starting interest rate swaps as of September 30, 2013 (notional amounts in millions):

	Hedged Transaction		Number and Types of		Notional			Expected		Average Fixed		Accounting
	Hedged Transaction		Derivatives Employed		Amount			Termination Date		Rate		Treatment
	Anticipated debt offering		10 forward starting swaps (30-year)		$	250		6/15/15		3.6	%	Cash flow hedge


	Concurrent with PAA’s August 2013 senior notes issuance, five thirty-year forward starting swaps were terminated. We received cash proceeds of approximately $11 million, of which a gain of approximately $8 million was deferred in AOCI and a gain of approximately $3 million was recognized in interest expense attributable to the ineffective portion, in connection with the termination of these swaps.

	During June 2011 and August 2011, PNG entered into three interest rate swaps to fix the interest rate on a portion of PNG’s outstanding debt. The following table summarizes the terms of these swaps (notional amount in millions):

	Hedged Transaction		Number and Types of		Notional			Termination Dates		Average Fixed Rate		Accounting
	Hedged Transaction		Derivatives Employed		Amount			Termination Dates		Average Fixed Rate		Treatment
	Floating interest rate payments associated with PNG outstanding debt		3 floating-to-fixed swaps		$	100		6/6/14		0.95	%	Cash flow hedge
			3 floating-to-fixed swaps		$	100		8/3/14		0.95	%	Cash flow hedge


	Currency Exchange Rate Risk Hedging

	Because a significant portion of our Canadian business is conducted in CAD and, at times, a portion of our debt is denominated in CAD, we use foreign currency derivatives to minimize the risks of unfavorable changes in exchange rates. These instruments include foreign currency exchange contracts and forwards. As of September 30, 2013, AOCI includes net deferred gains of approximately $1 million that relate to foreign currency derivatives that were designated for hedge accounting.

	As of September 30, 2013, our outstanding foreign currency derivatives include derivatives we use to (i) hedge CAD-denominated interest payments on CAD-denominated intercompany notes, (ii) hedge currency exchange risk associated with USD-denominated commodity purchases and sales in Canada and (iii) hedge currency exchange risk created by the use of USD-denominated commodity derivatives to hedge commodity price risk associated with CAD-denominated commodity purchases and sales.

Summary of Financial Impact

We record all open derivatives on the balance sheet as either assets or liabilities measured at fair value. Changes in the fair value of derivatives are recognized currently in earnings unless specific hedge accounting criteria are met. For derivatives that qualify as cash flow hedges, changes in fair value of the effective portion of the hedges are deferred in AOCI and recognized in earnings in the periods during which the underlying physical transactions are recognized in earnings. Derivatives that do not qualify for hedge accounting and the portion of cash flow hedges that are not highly effective in offsetting changes in cash flows of the hedged items are recognized in earnings each period. Cash settlements associated with our derivative activities are reflected as cash flows from operating activities in our condensed consolidated statements of cash flows.

A summary of the impact of our derivative activities recognized in earnings for the three and nine months ended September 30, 2013 and 2012 is as follows (in millions):

(1) During the three months ended September 30, 2013, we reclassified losses of approximately $2 million from AOCI to Facilities segment revenues as a result of anticipated hedged transactions that are probable of not occurring. During the nine months ended September 30, 2013, we reclassified gains of approximately $3 million and losses of approximately $1 million from AOCI to Supply and Logistics segment revenues and Facilities segment revenues, respectively, as a result of anticipated hedged transactions that are probable of not occurring. All of our hedged transactions were deemed probable of occurring during the three and nine months ended September 30, 2012.

Our derivative transactions are governed through ISDA (International Swaps and Derivatives Association) master agreements and clearing brokerage agreements. These agreements include stipulations regarding the right of set off in the event that we or our counterparty default on our performance obligations. If a default were to occur, both parties have the right to net amounts payable and receivable into a single net settlement between parties.

Our accounting policy is to offset derivative assets and liabilities executed with the same counterparty when a master netting arrangement exists. Accordingly, we also offset derivative assets and liabilities with amounts associated with cash margin. Our exchange-traded derivatives are transacted through clearing brokerage accounts and are subject to margin requirements as established by the respective exchange. On a daily basis, our account equity (consisting of the sum of our cash balance and the fair value of our open derivatives) is compared to our initial margin requirement resulting in the payment or return of variation margin. As of September 30, 2013, we had a net broker receivable of approximately $164 million (consisting of initial margin of $96 million increased by $68 million of variation margin that had been posted by us). As of December 31, 2012, we had a net broker receivable of approximately $41 million (consisting of initial margin of $69 million reduced by $28 million of variation margin that had been returned to us).

The following tables present information about derivatives and financial assets and liabilities that are subject to offsetting, including enforceable master netting arrangements at September 30, 2013 and December 31, 2012 (in millions):

As of September 30, 2013, there was a net loss of approximately $104 million deferred in AOCI including tax effects. The deferred net loss recorded in AOCI is expected to be reclassified to future earnings contemporaneously with (i) the earnings recognition of the underlying hedged commodity transaction, (ii) interest expense accruals associated with underlying debt instruments or (iii) the recognition of a foreign currency gain or loss upon the remeasurement of certain CAD-denominated intercompany balances. Of the total net loss deferred in AOCI at September 30, 2013, we expect to reclassify a net loss of approximately $28 million to earnings in the next twelve months. The remaining deferred loss of approximately $76 million is expected to be reclassified to earnings through 2045. A portion of these amounts are based on market prices as of September 30, 2013; thus, actual amounts to be reclassified will differ and could vary materially as a result of changes in market conditions.

The net deferred gain/(loss), including tax effects, recognized in AOCI for derivatives during the three and nine months ended September 30, 2013 and 2012 are as follows (in millions):

		Three Months Ended						Nine Months Ended
		September 30,						September 30,
		2013			2012			2013			2012
Commodity derivatives, net		$	66		$	88		$	77		$	88
Interest rate derivatives, net		12			8			64			(20		)
Total		$	78		$	96		$	141		$	68

At September 30, 2013 and December 31, 2012, none of our outstanding derivatives contained credit-risk related contingent features that would result in a material adverse impact to us upon any change in our credit ratings. Although we may be required to post margin on our cleared derivatives as described above, we do not require our non-cleared derivative counterparties to post collateral with us.

Recurring Fair Value Measurements

Derivative Financial Assets and Liabilities

The following table sets forth by level within the fair value hierarchy our financial assets and liabilities that were accounted for at fair value on a recurring basis as of September 30, 2013 and December 31, 2012 (in millions):

		Fair Value as of September 30, 2013												Fair Value as of December 31, 2012
Recurring Fair Value Measures (1)		Level 1			Level 2			Level 3			Total			Level 1			Level 2			Level 3			Total
Commodity derivatives		$	(11	)	$	(22	)	$	(1	)	$	(34	)	$	1		$	35		$	4		$	40

Total		$	(11	)	$	(5	)	$	(1	)	$	(17	)	$	1		$	(3	)	$	4		$	2

(1) Derivative assets and liabilities are presented above on a net basis but do not include related cash margin deposits.

Level 1

Level 1 of the fair value hierarchy includes exchange-traded commodity derivatives such as futures and options. The fair value of exchange-traded commodity derivatives is based on unadjusted quoted prices in active markets.

Level 2

Level 2 of the fair value hierarchy includes exchange-cleared commodity derivatives and over-the-counter commodity, interest rate and foreign currency derivatives that are traded in active markets. The fair value of these derivatives is based on broker price quotations which are corroborated with market observable inputs.

Level 3

Level 3 of the fair value hierarchy includes over-the-counter commodity derivatives that are traded in markets that are active but not sufficiently active to warrant level 2 classification in our judgment and certain physical commodity contracts. The fair value of our level 3 over-the-counter commodity derivatives is based on broker price quotations. The fair value of our level 3 physical commodity contracts is based on a valuation model utilizing broker-quoted forward commodity prices, and timing estimates, which involve management judgment. The significant unobservable inputs used in the fair value measurement of our level 3 derivatives are forward prices obtained from brokers. A significant increase (decrease) in these forward prices would result in a proportionately lower (higher) fair value measurement.

Rollforward of Level 3 Net Asset/(Liability)

The following table provides a reconciliation of changes in fair value of the beginning and ending balances for our derivatives classified as level 3 (in millions):

		Three Months Ended						Nine Months Ended
		September 30,						September 30,
		2013			2012			2013			2012
Beginning Balance		$	4		$	36		$	4		$	12

Included in earnings (1)		(4		)	(9		)	(1		)	(1		)
Included in other comprehensive income		—			—			—			3
Settlements		(1		)	(4		)	(3		)	(18		)
Derivatives entered into during the period		—			1			(1		)	23
Transfers out of level 3		—			(14		)	—			(9		)
Ending Balance		$	(1	)	$	10		$	(1	)	$	10

Change in unrealized gains/(losses) included in earnings relating to level 3 derivatives still held at the end of the periods		$	(4	)	$	(8	)	$	(1	)	$	25


(1) We reported unrealized gains and losses associated with level 3 commodity derivatives in our condensed consolidated statements of operations as Supply and Logistics segment revenues.

During the third quarter of 2012, we transferred commodity derivatives with an aggregate fair value of a $14 million gain from level 3 to level 2. These derivatives consist of over the counter derivatives that were previously valued using forward prices obtained from a broker and are now being valued using unadjusted quoted prices in active markets. Our policy is to recognize transfers between levels as of the beginning of the reporting period in which the transfer occurred.

During the second quarter of 2012, we transferred commodity derivatives with an aggregate fair value of a $5 million loss from level 3 to level 2. These derivatives consist of NGL derivatives that are cleared through the CME Clearport platform. This transfer resulted from additional analysis regarding the CME’s pricing methodology.

We believe that a proper analysis of our level 3 gains or losses must incorporate the understanding that these items are generally used to hedge our commodity price risk, interest rate risk and foreign currency exchange risk and will therefore be offset by gains or losses on the underlying transactions.

	Litigation

	General. In the ordinary course of business, we are involved in various legal proceedings. To the extent we are able to assess the likelihood of a negative outcome for these proceedings, our assessments of such likelihood range from remote to probable. If we determine that a negative outcome is probable and the amount of loss is reasonably estimable, we accrue the estimated amount. We do not believe that the outcome of these legal proceedings, individually or in the aggregate and including the general and environmental legal proceedings described below, will have a material adverse effect on our financial condition, results of operations or cash flows.

	Pemex Exploración y Producción v. Big Star Gathering Ltd L.L.P. et al. In two cases filed in the Texas Southern District Court in May 2011 and April 2012, Pemex Exploración y Producción (“PEP”) alleges that certain parties stole condensate from pipelines and gathering stations and conspired with U.S. companies (primarily in Texas) to import and market the stolen condensate. PEP does not allege that Plains was part of any conspiracy, but that it dealt in the condensate only after it had been obtained by others and resold to Plains Marketing, L.P. PEP seeks actual damages, attorney’s fees, and statutory penalties from Plains Marketing, L.P. At a hearing held on October 20, 2011, the Court ruled that Texas law (not Mexican law) governs the actions. In February 2013, the Court granted Plains Marketing, L.P.’s motion to be dismissed from the April 2012 lawsuit and Plains Marketing, L.P. filed a motion for summary judgment in the May 2011 lawsuit. In October 2013, the Court issued an order in the May 2011 lawsuit granting summary judgment in favor of Plains Marketing, L.P. with respect to all of PEP’s remaining claims against Plains Marketing, L.P.; shortly thereafter, PEP notified Plains Marketing, L.P. of its intent to appeal such ruling.

	Proposed Merger with PNG

	On September 13, 2013, Robert and Teresa Vicars, purported common unitholders of PNG, filed a class action petition on behalf of PNG’s common unitholders and a derivative suit on behalf of PNG against PAA, PNG’s general partner and the directors of PNG’s general partner in the 152nd Judicial District of Harris County, Texas (“Vicars”). A similar class action complaint was filed against the same defendants, together with PAA GP LLC, Plains All American GP LLC and Plains AAP, L.P., on September 17, 2013, in the Court of Chancery of the State of Delaware by purported PNG common unitholder Stephen Ellman (“Ellman”). On November 14, 2013, a similar class action and derivate lawsuit was filed against the same defendants as named in the Vicars suit in the 129th Judicial District of Harris County, Texas by purported unitholder Thomas Barbee (“Barbee”). A fourth class action complaint for breach of fiduciary duties was filed against the same defendants as in the Ellman Suit on November 15, 2013, in the United States District Court for the Southern District of Texas — Houston Division by purported unitholder Robert Evans, on behalf of himself and all others similarly situated (“Evans”, and collectively with Vicars, Barbee and Ellman, the “PNG Shareholder Suits”).

	The PNG Shareholder Suits complaints allege, among other things, that the consideration offered by PAA is unfair and inadequate and that, by pursuing a transaction that is the result of an allegedly conflicted and unfair process, the defendants have breached their duties under PNG’s partnership agreement as well as the implied covenant of good faith and fair dealing, and are engaging in self-dealing. These two lawsuits generally allege that: (i) the defendants are engaging in self-dealing, are not acting in good faith toward PNG, and have breached and are breaching their duties owed to PNG; (ii) the defendants are failing to properly value PNG and its various assets and operations and are ignoring or are not protecting against the numerous conflicts of interest arising out of the proposed transaction; and (iii) we, PNG’s general partner, PNG and other of our affiliates have aided and abetted the defendant directors the purpose of advancing their own interests and/or assisting such directors in connection with their breaches of their respective duties. In addition, Vicars and Evans further include (i) purported derivative claims on behalf of PNG based on the alleged breaches of duties by the defendants and (ii) a claim that the defendants breached the implied covenant of good faith and fair dealing by engaging in a flawed merger process. In Barbee and Evans, the complaints allege, among other things, that the implied price per unit materially undervalues PNG and is unfair to its unitholders and that the S-4 registration statement filed by PNG was materially misleading. The PNG Shareholder Suits plaintiffs further allege that the defendants who are directors and officers of the general partner of PNG have breached their fiduciary duties of loyalty and care and the other defendants have aided and abetted in these alleged breaches. Based on these allegations, the plaintiffs generally seek to enjoin the defendants from proceeding with or consummating the merger. To the extent that the merger is implemented before relief is granted, plaintiffs seek to have the merger rescinded. The plaintiffs also seek money damages and attorneys’ fees.

	We cannot predict the outcome of these or any other lawsuits that might be filed, nor can we predict the amount of time and expense that will be required to resolve these lawsuits. We intend to defend vigorously against these and any other actions. See Note 1 for a description of our proposal to acquire all of the outstanding common units of PNG that are held by unitholders other than us or our subsidiaries and to structure the proposed transaction as a merger with PNG.

	Environmental

	General. Although we believe that our efforts to enhance our leak prevention and detection capabilities have produced positive results, we have experienced (and likely will experience future) releases of hydrocarbon products into the environment from our pipeline and storage operations. These releases can result from unpredictable man-made or natural forces and may reach “navigable waters” or other sensitive environments. Whether current or past, damages and liabilities associated with any such releases from our assets may substantially affect our business.

	At September 30, 2013, our estimated undiscounted reserve for environmental liabilities totaled approximately $99 million, of which approximately $13 million was classified as short-term and approximately $86 million was classified as long-term. At December 31, 2012, our reserve for environmental liabilities totaled approximately $96 million, of which approximately $13 million was classified as short-term and approximately $83 million was classified as long-term. The short- and long-term environmental liabilities referenced above are reflected in “Accounts payable and accrued liabilities” and “Other long-term liabilities and deferred credits,” respectively, on our condensed consolidated balance sheets. At September 30, 2013 and December 31, 2012, we had recorded receivables totaling approximately $10 million and $42 million, respectively, for amounts probable of recovery under insurance and from third parties under indemnification agreements, which are predominantly reflected in “Trade accounts receivable and other receivables, net” on our condensed consolidated balance sheets.

	In some cases, the actual cash expenditures may not occur for three to five years. Our estimates used in these reserves are based on information currently available to us and our assessment of the ultimate outcome. Among the many uncertainties that impact our estimates are the necessary regulatory approvals for, and potential modification of, our remediation plans, the limited amount of data available upon initial assessment of the impact of soil or water contamination, changes in costs associated with environmental remediation services and equipment and the possibility of existing legal claims giving rise to additional liabilities. Therefore, although we believe that the reserve is adequate, costs incurred may be in excess of the reserve and may potentially have a material adverse effect on our financial condition, results of operations or cash flows.

	Rainbow Pipeline Release. During April 2011, we experienced a crude oil release of approximately 28,000 barrels of crude oil on a remote section of our Rainbow Pipeline located in Alberta, Canada. Since the release and through September 30, 2013, we spent approximately $70 million, before insurance recoveries, in connection with site clean-up, reclamation and remediation activities, and as of September 30, 2013, we did not have any material outstanding liabilities or insurance receivables relating to this release. On February 26, 2013, the Alberta Energy Regulator (formerly known as the Energy Resources Conservation Board of Alberta) (“AER”) issued a report detailing four enforcement actions against Plains Midstream Canada ULC (“PMC”) for failure to comply with certain regulatory requirements in connection with the release, including requirements related to operations and maintenance procedures, leak detection and response, backfill and compaction procedures and emergency response plan testing. PMC is in the process of taking appropriate actions necessary to respond to and comply with the enforcement actions set forth in the report, including the implementation of additional risk assessment procedures and the taking of other actions designed to minimize the risk that similar incidents occur in the future and enhance the effectiveness of PMC’s response to any such future incidents. In addition, on April 23, 2013, the Alberta Crown Prosecutor filed civil charges under the Environmental Protection and Enhancement Act against PMC relating to the release. To date, PMC has not been assessed any fines or penalties related to this release; however, such fines or penalties may be assessed in the future and are not expected to be material.

	Rangeland Pipeline Release. During June 2012, we experienced a crude oil release on a section of our Rangeland Pipeline located near Sundre, Alberta, Canada. Approximately 3,000 barrels were released into the Red Deer River and were contained downstream in the Gleniffer Reservoir. Remediation activities in the reservoir area were completed by June 30, 2012, remediation of the remaining impacted areas was completed by September 30, 2012 and interim closure was received from the applicable regulatory agencies. Monitoring will continue into 2013, and a long-term monitoring plan has been developed and implemented in accordance with regulatory requirements. Through September 30, 2013, we spent approximately $46 million, before insurance recoveries, in connection with site clean-up, reclamation and remediation activities, and as of September 30, 2013, we did not have any material outstanding liabilities or insurance receivables relating to this release. This release is currently under investigation by the AER, which also intends to perform an audit of PMC’s operations. Although the AER’s final investigation is not complete, on July 4, 2013, the AER issued a report detailing four enforcement actions against PMC citing failure to inspect water crossings, failure to complete an engineering assessment to determine suitability of continued operation of the Rangeland Pipeline, failure to maintain updated emergency response plans, and failure to conduct regular public awareness programs. The AER also issued an order under Section 22 of the Oil and Gas Conservation Act imposing additional regulatory requirements on PMC with respect to obtaining operating approvals under such Act and ordering audit of PMC’s operations. To date, no fines or penalties have been assessed against PMC with respect to this release; however, it is possible that fines or penalties may be assessed against PMC in the future and are not expected to be material.

	Bay Springs Pipeline Release. During February 2013, we experienced a crude oil release of approximately 120 barrels on a portion of one of our pipelines near Bay Springs, Mississippi. Most of the released oil was contained within our pipeline right of way, but some of the released oil entered a nearby waterway where it was contained with booms. The EPA has issued an administrative order requiring us to take various actions in response to the release, including remediation, reporting and other actions, and we may be subjected to a civil penalty. The aggregate cost to clean up and remediate the site was approximately $6 million, which has been recognized in “Field operating costs” on our condensed consolidated statement of operations.

	Kemp River Pipeline Release. During May and June 2013, two separate releases were discovered on our Kemp River pipeline in Northern Alberta, Canada that, in the aggregate, resulted in the release of approximately 700 barrels of condensate and light crude oil. Clean-up and remediation activities are being conducted in cooperation with the applicable regulatory agencies. We estimate that the aggregate clean-up and remediation costs associated with these releases will be approximately $15 million which we have accrued to “Field operating costs” on our condensed consolidated statement of operations.

	We manage our operations through three operating segments: (i) Transportation, (ii) Facilities and (iii) Supply and Logistics. Our Chief Operating Decision Maker (our Chief Executive Officer) evaluates segment performance based on measures including segment profit and maintenance capital investment. We define segment profit as revenues and equity earnings in unconsolidated entities less (i) purchases and related costs, (ii) field operating costs and (iii) segment general and administrative expenses. Each of the items above excludes depreciation and amortization. The following table reflects certain financial data for each segment for the periods indicated (in millions):

	Occidental Petroleum Corporation

	As of September 30, 2013, a subsidiary of Occidental Petroleum Corporation (“Oxy”) owned approximately 35% of our member interest and had a representative on our board of directors. In October 2013, in conjunction with PAGP’s IPO, Oxy sold a portion of its interest, decreasing its ownership to approximately 25%. See Note 15 for further discussion of PAGP’s IPO. During the three and nine months ended September 30, 2013 and 2012, we recognized sales and transportation revenues and purchased petroleum products from companies affiliated with Oxy. These transactions were conducted at posted tariff rates or prices that we believe approximate market. See detail below (in millions):

	Note 14—Impairments

	During the third quarter of 2012, we recognized losses on impairments of long-lived assets of approximately $125 million, primarily related to our Pier 400 terminal project, which is reflected in “Depreciation and amortization” on our condensed consolidated statement of operations. This project, which we acquired in late 2006 by virtue of our merger with Pacific Energy Partners, L.P., was to develop a deepwater petroleum import terminal at Pier 400 and Terminal Island in the Port of Los Angeles to handle marine receipts of crude oil and refinery feedstock. During the third quarter of 2012, we decided not to proceed with the development of this project. A number of factors contributed to the uncertainties with respect to financial returns and the determination not to proceed with the project, including project delays, the economic downturn, regulatory and permitting hurdles, a challenging refining environment in California and an industry shift in the outlook for availability of domestic crude oil. We assessed the recoverability of these long-lived assets and, where necessary, performed further analysis based on a projected discounted cash flow methodology. As a result of this impairment review, we wrote off a substantial portion of the carrying amount of these long-lived assets, except for the portion that we anticipate we will recover. These project assets were included in our Facilities segment.

	During the three and nine months ended September 30, 2013, we recognized impairments of approximately $8 million and $15 million, respectively, related predominantly to assets taken out of service and canceled projects.

	Initial Public Offering

	Through a series of transactions with PAGP’s general partner and the owners of GP LLC prior to the closing of the IPO in October 2013, PAGP issued 473,647,679 Class B Shares to such owners and received a 100% managing member interest in GP LLC. Also prior to the IPO, certain owners of AAP (the “Selling Owners”) sold a portion of their interests in AAP to PAGP in exchange for the right to receive an amount equal to the net proceeds of the IPO, resulting in PAGP’s ownership of an approximate 21.8% limited partnership interest in AAP.

	In October 2013, PAGP completed its IPO of 132,382,094 Class A Shares representing limited partner interests (including 4,382,094 Class A Shares issued in connection with the partial exercise of the underwriter’s overallotment option), at a price of $22.00 per Class A Share, generating net proceeds, after deducting underwriting discounts and commissions and direct offering expenses, of approximately $2.8 billion. The net proceeds of the offering were distributed to the Selling Owners. The Class A Shares are listed on the New York Stock Exchange under the symbol “PAGP.” PAGP has elected to be treated as a corporation for U.S. federal income tax purposes.

	Administrative Agreement

	In conjunction with PAGP’s IPO in October 2013, PAGP entered into an administrative agreement with PAA and certain of its affiliates, pursuant to which PAGP agreed upon certain aspects of its relationship with them, including, among other things (i) that if any business opportunity is presented to the parties to the agreement, PAA will have the first right to pursue such business opportunity, (ii) that GP LLC will employ such personnel as may be necessary to manage and operate the business, properties and assets of PAGP, its general partner and AAP, and AAP will pay GP LLC an annual fee (initially, $1.5 million per year, subject to adjustment as specified in the agreement) for such general and administrative services, (iii) that any direct expenses incurred by PAGP, its general partner or AAP (other than income taxes payable by PAGP), will be borne by AAP, (iv) that AAP will reimburse GP LLC for any additional expenses incurred by GP LLC and certain of its affiliates, and (v) that PAA has granted PAGP use of the name “PAA” and “Plains” and any associated or related marks.

	Plains GP Holdings, L.P. Long-Term Incentive Plan

	In connection with PAGP’s IPO in October 2013, its general partner adopted the Plains GP Holdings, L.P. Long-Term Incentive Plan (the “PAGP Plan”), which is intended to align the interests of PAGP’s employees and directors with those of its shareholders by providing such employees and directors incentive compensation awards that reward achievement of targeted distribution levels and other business objectives. The PAGP Plan provides for awards of options, restricted shares, phantom shares and share appreciation rights. Certain awards may also include distribution equivalent rights, which, subject to applicable vesting criteria, entitle the grantee to a cash payment equal to the cash distribution paid on an outstanding Class A Share. The PAGP Plan authorizes the issuance of up to 10 million Class A Shares deliverable upon vesting. As of the date of this report, no awards had been granted under the PAGP Plan.

	(1) In 2013, we renewed and extended our principal bank credit facilities. See “Credit Facilities” below for further discussion.

	(2) We classify as short-term certain borrowings under the PAA commercial paper program, PAA senior unsecured revolving credit facility and PAA senior secured hedged inventory facility. These borrowings are primarily designated as working capital borrowings, must be repaid within one year and are primarily for hedged NGL and crude oil inventory and NYMEX and ICE margin deposits.

	(3) We classify as short-term debt any borrowings under the PNG senior unsecured revolving credit facility that have been designated as working capital borrowings and must be repaid within one year. Such borrowings are primarily related to a portion of PNG’s hedged natural gas inventory.

	(4) PAA’s $250 million 5.63% senior notes will mature in December 2013 and are thus classified as short-term at September 30, 2013 and December 31, 2012.

	(5) In August 2013, PAA completed the issuance of $700 million, 3.85% senior notes due 2023 at a public offering price of 99.792%. Interest payments are due on April 15 and October 15 of each year, commencing on April 15, 2014.

	(6) PAA’s fixed-rate senior notes (including current maturities) had a face value of approximately $7.0 billion and $6.3 billion at September 30, 2013 and December 31, 2012, respectively. We estimated the aggregate fair value of these notes as of September 30, 2013 and December 31, 2012 to be approximately $7.5 billion and $7.3 billion, respectively. PAA’s fixed-rate senior notes are traded among institutions, and these trades are routinely published by a reporting service. Our determination of fair value is based on reported trading activity near quarter end. We estimate that the carrying value of outstanding borrowings under our credit agreements and commercial paper program approximates fair value as interest rates reflect current market rates. The fair value estimates for our senior notes and borrowings under our credit agreements and commercial paper program are based upon observable market data and are classified within level 2 of the fair value hierarchy.
